.iframe 2 are of the usual construction andthe details of their construction .and configuration depend entirely upon'the kind-ot'loom used.l lhe spool is shown rather shorter than is customary so that for the purpose-'0f clearness ot'V illustration a larger scale may ranged on the carriage that it will-hold the ends ot' the tutt ya rhs distended horizontallv from the spool. strip ot' wood 7 is arranged so as to press the yarns upon the brush therebyY serving?r the purpose of a guide or Clamp to holdthe tree ends of the tutt, yarns separat-e and in proper order, the Strip of wood T serving as a clamping part rexno\ ably connected 'thereto and adapted.when in place` to tit orer the sinxces -between the bristles ol the brush and clamp the yarnl separated and in propel' order. 'lhiswooden strip is shown as supported upon arms T', hinged at 73. 7g is a wheel adaptedtoengage with the rail l. to press down the .strip 7 as is The 'spool is supported within the holder S b v'the engagement oit' itsl axle 1 with a slit b and is pro- 'vided with al ratchet wheel 9 which engages with a pawl l() mounted on the carriage so that it cannot be rotatedexeept in the'di1'ee-- tion to wind up th e \'ar1 1. The tubes 1l are supported by the frame 2 inthe usual'manner vamt-are Vkept in proper/alinement b v a comb-shaped piece ot' metal l2. provided' with notches.' which engage with and separate the tubes. 'lfhe comb l2 is rigidly secured to the carriage Il.' The tubes 11 arel remorably carried by the frame 2 so that the spooll and tubes may be removed from the. machin -1 and placed in the loom without 'ldisturbing` the yarns after they have been threaded through the tnb'es.

It will be noticed in this machine that the tubes l1 are not round buto\'alshaiped and areelosely connected together. 'This makesit necessary to arrange the needle so that its longest'eross section will be parallel lo the The carriage 3 is adapted to travel from left to right and vice versa on the rails 4, 5, by mechanism about to be described.

The thread needle 13 is carried upon a slide 14 which travels in ways 14 and is operated by an arrangementof levers 15, 16 and lif, the latter being engaged by an eccentric 18 -which is mounted upon a shaft 19, the lever4 15 being pivoted at 15. The needle is adapted to be moved upward and downward through whichever tube 11 is at the tlme being above it... It will there receive thethread and will draw the latter down through the tube. Atinger 2O earried by a lever 21 is arranged to pull the thread from the needle by the downward movement of thelatter after it has passed downward through the tube, such lever being actuated by engagement with the lever 15.

In operation the carriage is placed in position at the eXtreme left side of the machine and is intermittently moved to the right so as to bring the tube successively over the needle which is alternately elevated and depressed passing successively through the dif ferent tubes, engaging with the tutt yarn which is above the tube and drawing it down through the tube. The yarn becomes -disenfra ed from thevneedle. b engagement b H 23 rack 27, which is tiXed to the frame of the carriage. A projection 2S on the cam Q9, which is supported upon the shaft 19, is so arranged as to engage with a friction roller 29l on the dog 22 and elevate it when the needle lis in the lowermost position, as shown in Fig. 3. This will cause the pawl 24; to

act upon one of the lowermost teeth 26..

`When the dog 2Q is lowered -the upper pawl 23 engages with a new notch 25, and this is kept up so long` as the shaft 19 is rotated successively and intermittently moves the rack 27 to the right and with it the carriage.

Supported upon the frame of the machine is a supplemental carriage 31 which is arranged to'separate thethreads one by one, or when occasion demands it, two by two, and pull the separated thread to one side so that it will be engaged by the needle as the latter descends. tut threads which have been previously stretched between the brush (i and ,spool 1 enter between the beveled edge plates 32, The space between these plates is little more than the thickness of one thread so To secure this result, the

' this being done.

small supplemental brushes 34 and 35 are provided and these brushes are turned by gear wheels 3G and 3T from the shaft 19.

sprocket wheels 3S and 39 and a chain 40- and gear wheels 41 and 42.. These brushes will successively engage with the tutt yarns as they are about to enter between the plates 3Q, 33, and will straighten out any yarns which are not in proper position. The supplemental carriage 31 is mounted in fixed slides L13, 44, so that it may be moved a short distance from right to left and vice \'ersa.-

.moving to the right they will bring it in trout of the hook ct the needle which at this time is elevated. Tt will be noticed that the hook of the needle is turned toward the brushes. The thread will tirst engage .with

a pin 49 carried by the slide 43 so that the thread will not get upon the wrong side ot the needle. As the needle descends its hook engages lwith the tuttyarn to the right and draws it` through the tube. The vertical plate 4S is arranged to be moved up and down. lt is mounted in slides 42S on the frame 31 and il is engagml with the cam surfaces it), :31, cut out from thel slides 4:3, 44. So mounted it will he seen that'the plate 4S will rise when the'carriage 31 is moved to the right. This will cause a iinger which is fastened to the plat-e and which. extends outside of the hooks to engage with the thread and push it into a notch 53 cut in the platell'b. Thus it will be seen that the yarn is kept away :fi-mn the free eXtremi ties of the hooks when it is drawn down by the needle and all danger ot' the yarn engaging with the hooks is avoided. The hooks are secured to the supplemental carriage 31 by a plate 54, which is provided with a securing screw 55 by-mcans of which they may be adjusted. The space between the plate 4S and thc points of the hooks should be. sidistantially the thickness ol one yarn. Tf two yarns or morey are to be threaded in each tube the space mentioned must be made sutiiciently large to permit This can be regulated by adjusting the hooks by means of the supporting screw 55. The supplemental carriage 31 may beoperated in an manner, the means illustrated consisting ot an. eXtension of the lever 15, the cord 56 and retracting spring 57. The cord 56 is secured to the rear face of the supplemental carriage and leads. over a guide pulley carried at the right hand end of the fixed slideway 43,

thence over another guidepulley at the rear of the machine-2 to the extension ot the lever l5. The spring is secured to'lhel front 'of the supplemental carriageand tothe lett hand end ot the-slideway. a?. so that l`its tendency will be to hold 't-hecarria'gefto the left side .of the slideivays.funtilfthe.eX!A

tension of `thelever ,l5 is depressed-by-its springwhen the carriage will be drauf-n by' the cord 56 to the right hand` endet the Slideiv'ays. 'l he operating means for the supplementalcarriage is adjusted. to move it to'its 'extreme lett hand position when the, needle is depressed, and to its eXtreme right hand'p'osition .v vhen the needle is elevated.

, The shafts 'of the circularbrushesa'nd the slides 4 3, 44, are held stationary bya support 58, which is fastened to the table 59 of the -inachii'ie .Upon this table 'all otithe fixed parts 'of the machine are secured.

.Asshown in Fig. 3, lthe dog is provided with a. slot. (ll.y Which engages with a pin (35 onthetable 59, and about which it may pivot,- 'w'hen it is desired to -disengagei theratchetsjtrom the ra'ck 27.

In one sidel of the' fast pulley 70 is a' slot Tl extending the lengthv thereof and Working ivithin this slot is aslide T2 of a length some.- ivhat greater than that of the pulley TG. vBy

,means of .a rib projecting through a narrow slot Irthe slide has secured thereto cain .plate 74 lwhich covers a portion of. the tace ofthe pulley 7 0 and by means of which the slide `may Vbe moved to cause its project# ing end to project from one side or the'oth'er ofthe fixed pulley.

.The cam plate is moved by the arms and ,TG carried by the sliding shaft G8, as shoivn in Fig. 8 and these arms are so constructed as td limit the extent ofmovement" of the cam plate.

Secured to one side of the loose pulley 61 an abutment 77 .With Avfhichvthe slide 72- engages .vhen it is desired to loclrth'e fast fand loose pulleys together and start the ma chine. The slide maybe locle'd in engagementv with the abutment by means otl a spring pressed latch 78 pivoted to the side of the loose pulley.

-Pivcted in the bearing plate 69 at the side of the pulley 70 opposite tothe abutment 77 is a spring actuated brakeVT'Q'prOVided "With a uotchB tor engagement yvith the' slide- 72,
